The Hubble Space Telescope is
STScI's first major mission. Here you'll find instrumentation descriptions, instructions
for writing and submitting observing proposals, how to retrieve and analyze HST data,
and images from the telescope.

The Institute offers a wide range of information services and software tools to astronomers
and the public. Many of these resulted from our work on the HST mission, others are initiatives
of our scientific and technical staff, and still more will come from our work on JWST and
future missions.
